Core Tip

Core Tip: Localized gastric amyloidosis (LGA) is rare. Few case reports are available to the public. It is often misdiagnosed as other gastrointestinal diseases due to its atypical manifestation. However, no systemic reviews or guidelines of LGA is published now. Therefore, we present a detailed overview from its clinical manifestations to prognosis for the first time. Based on that, a clinical diagnostic procedure is provided and may benefit clinicians who manage LGA.
